摘要： A temporary keratoprosthesis, a corneal transplant suturing jig, a temporary endoprosthesis, methods of using the same, and kits comprising the same. The temporary keratoprosthesis and corneal transplant comprise grooves into which sutures are located during ophthalmological surgery such that the sutures are prevented from migrating and/or obscuring a view into the eye during surgery. The temporary keratoprosthesis, corneal transplant suturing jig, and temporary endoprosthesis are employed alone or in unison to maintain intraocular pressure during surgery.

摘要： Needle injectors and injector carriers for endothelial keratoplasty are provided. Needle injectors include first, second, and third portions each having a respective conduit therein. A first end of the second conduit is fluidly coupled to a second end of the first conduit, where the second conduit has a maximum diameter greater than a maximum diameter of the first conduit. A first end of the third conduit is configured to be fluidly coupled to a second end of the second conduit, where a second end of the third conduit is configured with a cutting surface for cutting and penetrating eye tissue. Injector carriers include a container, a cap configured to seal an opening of the container, and a coupling means configured to couple the needle injector to the cap and allow the needle injector to be disposed within the container.

摘要： A device for manipulating an implant includes a handle coupled to a guide extending from the handle to a distal end. The device includes an engagement mechanism disposed at the distal end of the guide and configured to engage an implant. The device includes a first actuator disposed on the handle and coupled to the engagement mechanism. The first actuator causes the engagement mechanism to engage the implant. The device includes an air chamber disposed in an interior chamber of the handle and configured to hold air. The device includes a lumen coupled to the air chamber and extending along the guide to the distal end. The lumen includes an air channel extending through the lumen. The device includes a second actuator disposed on the handle. The second actuator causes the air chamber to deliver the air, via the air channel, to the distal end.

摘要： A method for treating hyperopia or presbyopia in a patient, the method comprising making a cut deep in the patient's cornea to create a two-dimensional slit adjacent to and generally parallel to an anterior surface of the cornea and injecting a liquid or semi-solid transparent filler material into the deep cut in an amount sufficient to flatten the posterior surface of the cornea to increase the refractive power of the cornea by a predetermined correction of up to about 5 diopters due to the physical flattening of the posterior surface of the cornea, wherein the transparent filler material comprises a refractive index of about 1.3 to about 1.6, and forms a corneal implant with a lenticular shape within the cornea.

摘要： A method of corneal lenslet implantation with a cross-linked cornea is disclosed herein. In one or more embodiments, the method includes the steps of: (i) forming a two-dimensional cut into a cornea of an eye; (ii) creating a three-dimensional pocket in the cornea of the eye in tissue around the two-dimensional cut to gain access to tissue surrounding the three-dimensional pocket; (iii) applying a photosensitizer inside the three-dimensional pocket so the photosensitizer permeates at least a portion of the tissue surrounding the three-dimensional pocket to facilitate cross-linking of the tissue surrounding the three-dimensional pocket; (iv) irradiating the cornea to activate cross-linkers in the portion of the tissue surrounding the three-dimensional pocket, and thereby stiffen the cornea, prevent corneal ectasia of the cornea, and kill cells in the portion of the tissue surrounding the three-dimensional pocket; and (v) inserting a lens implant into the three-dimensional pocket through a small corneal incision.

摘要： An optical accommodating system for an eye includes a sensor assembly and an adjustable optic assembly. The sensor assembly includes a sensor configured to sense a movement of the ciliary muscle and produce a signal, an electronic processor, a transmitter and a power source. The adjustable optic assembly is configured to be either implanted within or on the eye, or configured to be disposed adjacent to or near the eye. The adjustable optic assembly includes a switchable optical lens assembly configured to change its optical power between a first state and a second state, a receiver configured to receive the transferable signal from the transmitter of the sensor assembly, a second electronic processor connected to the receiver which directs the switchable optical lens assembly to change its optical power between the first state and second state, and a second power source connected to the second electronic processor.

摘要： Described herein is an extension device to extend ocular tissue within an irideocorneal angle of an eye of a patient, comprising a flexible body and a plurality of tensioning features disposed on the body. The body is sized and configured to be disposed within the irideocorneal angle. The body has a curved longitudinal axis, a channel extending from a first end to a second end, an inner convex side, and an outer concave side. The body is flexible between a first flexed condition and a second unflexed condition. The body has a first radius of curvature in the first flexed condition and a second radius of curvature in the unflexed condition. Each tensioning feature is shaped and sized to grasp the ocular tissue within the irideocorneal angle.
